BESIJLIENT HEEL OR HEEL-LIFT.

Application filed September 26. 1917.

To all whom it may concern:

Be it known that I, Riyuoxn Him, a citizen of the l nited States, residing at lllyria. in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in. Resilient Heels or Heelliifts; and I do hereby declare the tollowing to be a full. clear. and exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

idy invention relates to resilient heels or heel hits to be attached to boots or shoes. and more particularly such devices made of rubber or rubber composition.

One of the objects of my invention is to effect of such devices,

jars experiordinary heels or heel lifts. i also aim to produce a device which will realize the improved cushion eilect and which at the same time will be convenient and cheap to manu- I also aim to use a minimum of material and to reduce the weight of the eels.

Other objects or my invention and the invention itself will be better understood from a description of an embodiment of the invent'ion.

Figure 1 is a plan view of the face 01 aneinbodiment of my invention. Fig. 2 is a plan view of the tread surface of the embodiment of my invention shown in Fig. 1, and Fig. 3 is a section through the line 33 of the embodiment shown in Fig. 1.

eferring now to the drawing and to the embodiment of the invention shown therein, at 4 is shown the body portion of the heel lift made of some resilient material prefen ably of rubber or rub'er composition, and which has the outline of a shoe heel. The thickness of the embodiment shown in the drawing is that of about three lifts oil leather, though it will be readily understood that the thickness of the lift as desired. In the embodiment shown the tread surface 5 is shown as substantially flat, but the attaching surface 6 is shown concave and rovided with a raised margin 7 on the edge t ereof, which permits a certain amount of trimming of the lift'to fit shoes of various sizes and also admits of a certain amount of compression tossed the edge of the seam between the rubber and the leather.

attaching heel section to the shoe.

may be varied Specification of Letters Patent.

Patented Jan. 20, 1920. Serial No. 193.233.

A. plurality of members 8 project from the attaching suriace'ot' the heel. These members yield when weight is placed upon the heel, aiding in the cushioning effect 01 the resilient material. The utility of the device is greatly increased by placing the tops 9 of the members 8, all in substantially the same plane, so that the top of each member will always engage the part of the shoe to which the heel is attached, insuring better cooperating action of all of the members in producing this cushioning effect.

In the embodiment shown the members 9 are 'webs running in different directions across the attaching face of the heel, but extending only part way across, a space 10 be ing left at the, margin all about the heel to permit a certain amount of trimming of the lift to fit the shoe heel without iiljuring the projecting members. A. plurality of cells are thus formed in the attaching surface of the lift in which air is trapped and which aids in the cushioning effect of the projec- In the embodiment shown these webs run diagonally across the attaching surface of the heel, some at right angles to others, thus forming square cells, though it will be obvious that any suitable shaped cells may be employed. Of course, the number of cells, the thickness and the strength of the projections, as well as the shape of the projections may be varied without departing from the spirit of my invention.

Openings are shown at 14 through which nails or screws are applied to atthch the When nails or screws are applied, the margin 7 should be slightly compressed so that in endeavoring to return to normal position, it tends to keep closed the edge of the seam between the rubber and leather sections.

have found by actual experiment that the cushioning effect of the heel is greatly increased over that of the ordinary rubber heel or heel lift. Plugs 11 may be used. I prefer to make them of cork,.t-hough any suitable material and any suitable number of plugs may be employed.

As will be appreciated, the lift can be made in molds in the usual manner. Owing to the recesses formed between the projections, I am able to reduce the weight of the heels well as the amount of stock required to make them.

i. have shown this particular embodiment reference to the transverse of my invention and these details for the purpose of (,lcscribing the invcntion. It will be understood that many departures may be made from both the form and details without departing from the spirit of the. invention.

l-claim l. A resilient heel or heel section having a concave attaching face which is provided with upstanding yieldable intersecting webs substantially normal to the tread t'acc,'the webbed portion being substantially centrally aml s \'mmetricall v disposed with retercnce to the margin of the heel.

2. A resilient heel or heel section having a concave attaching face which is provided with closely associated intersecting yieldable webs extending at substantially right angles to one another and to the tread face of the heel. the webbed portion being substantially centrally and symmetrically disposed with short axis of the heel.

3. A resilient heel or heel section having a concave attaching face which is provided with upstanding intersecting webbing, the webbed portion conforming substantially to the shape of the heel or heel section and being substantially synunetrically dis osed with reference to the transverse centra axis of the heel.

l. A resilient heel or heel section having a concave attaching face which is provided with upstanding intersecting Webs substantially normal to the tread face, the webbed portion conforming in outline substantialli to the outline of the heel or heel section and substantially symmetrically disposed with reference to the transverse central axis of the heel and there being anunwebbed marginal portion outside of the webbed portion.

In witness whereof I have hereunto set my hand this 24 day of September, 1917.
